Great kit great quality
Great kit almost comes with everything, but you need to know you have to buy the thermostat housing gasket if you want to do it with the timing belt and water pump job.

What's most important to know
Everything necessary fof timing belt and water pump change. The only thing to remember is that you should also buy a new replacement serpentine belt for the alternator, if you wsng to do a proper job.

I installed this AISIN timing belt kit with water pump on my 2UZ‑FE and it went in smoothly, fit perfectly, and all the parts felt like solid OEM quality. Belt tension and tooth profile were spot‑on and the water pump sealed right up without any drama. 💡 Real 2UZ‑FE timing belt tips that matter: • Mark and re‑check timing marks carefully. Align the crank and cam sprocket marks with the belt marks, then rotate the engine at least two full rotations by hand before you torque anything down to make sure everything lines up exactly — if it doesn’t, take it off and try again. • Replace the water pump with the belt kit. The water pump is driven by the timing belt, and letting a worn pump go can shorten the life of your new belt. • Clean all pulley surfaces before install. Wipe oil and coolant off the crank, cam, idler, and water pump pulleys — don’t let contaminants interfere with seating and timing. • Use a torque wrench on key fasteners. Crank pulley, tensioner, and water pump bolts all have specific torque specs — meet them to avoid loosening or over‑stress. This job isn’t always a quick afternoon — getting into the timing cover can be the longest part — but doing it right will save headaches later. If you’re tackling a 2UZ‑FE belt job yourself, this AISIN kit plus these tips make a solid combo that keeps you confident you did it right.

Quality items in the kit, made in Japan and not China so it fit like OEM. Almost twice the cost of the knock off Chinese ones but worth it IMO, sometimes it better to pay more and have to do it once.

Fit the Toyota tundra 2007 perfectly. Very nice kit Asian is also majority owned by Toyota so you are getting oem product. Skip the dealer if you need this kit.

I have been a shade tree mechanic since 14 years old, at 67 years old Toyota wanted $1600 to change out my timing belt and all these components. So I bought this and did it myself and saved a lot of money, thanks to these parts and YouTube !!!!!
